We are the largest ham radio DX club in Arizona with over 130 members, many of whom are on the ARRL's DXCC Honor Roll.  We have several members who have traveled to distant places to put "rare" countries on the air.  We encourage any ham interested in DXing to join our club and learn about the many aspects of talking to hams around the globe who share this amazing hobby with us.  Founded in 1974, we are an ARRL-affiliated club and a member club of the Amateur Radio Council of Arizona (ARCA).

The March Meeting will be held on Thursday night, March 1st, at the PERA Club.  Our program will be "Getting to 3,000 in the DXCC Challenge", presented by Ned Stearns,  AA7A.  As many of you know, Ned recently reached the rarified air of the "3,000 Club" in the DXCC Challenge, the first ham in W6/W7 to do so.  There is nobody else in CADXA above the 2,800 mark and we have some very accomplished DXers in our ranks.  Ned will describe his DX journey through the years with help from some fascinating progress charts and anecdotes.    

Please feel free to arrive early to socialize with your friends.  Refreshments will be served at the break.  Guests are always welcome.

Feb. Meeting Recap

CADXA Repeater and Net
Join us on the K5VT repeater to announce and discuss DX.  In addition, there is a Thursday night net at 7:00 pm except on CADXA meeting nights.  The repeater and net are open to all DX enthusiasts.   
147.32 MHz (+) no PL tone

Our program on software defined radios (SDRs) was delivered via TeamViewer all the way from Toronto, Canada by Mike Walker, VA3MW, Sales Manager for FlexRadio. 


Mike gave us an impressive display of the advantages of "smart" SDRs that allows for easy adjustment of filter skirts and noise blanking for better reception.  He also demonstrated how RF power out on SSB can be maximized with SDR adjustments.


Mike made the point that an SDR radio can now be looked at as a "server" that supports a variety of functionality -- a totally different way of thinking about how a ham shack is configured locally or remotely.


Of course, Mike spent some time extolling the virtues of the various FlexRadio models and how the new Maestro gives hams the feel of a typical radio, but with all of the advantages of an SDR.


For those members who already own FlexRadio models, Mike made them feel good about their investment.  For the rest of us, he gave us a lot to consider about how the equipment in our hobby is rapidly evolving to keep pace with the technological advances surrounding us.

March Meeting

From ARCA

This past month was definitely one with “good news and bad news” for DXers.   The bad news first – the long awaited DXpedition to Bouvet Island in the Antarctic, 3Y0Z, never made it to land.  After two weeks of travel on some of the roughest ocean in the world, the ship was only a mile from Bouvet.  However, the weather was so extremely bad that, after two days of waiting for a break in the weather, the ship’s captain aborted the trip and set sail for South Africa, the closest port.  This was a huge disappointment to the brave hams and crew on board the ship and to the international DX community.  It is the first time in recent memory that a $1 million DXpedition was aborted.  The landing on Bouvet relied on helicopters that could not fly in the 45 knot winds and one of the two ship’s engines was failing, making the captain’s decision understandable with everyone’s lives at stake.  We wish the team and crew safe passage to ZS and back home.

The good news – a new DXCC country was born in late January 2018 after the ARRL Board amended the DXCC rules to add an additional country criteria that allowed Kosovo to be added to the country list.  Long a source of debate and controversy, the international team assembled by Martti Laine, OH2BH, began operating Z60A within minutes of the announcement and the pile-ups of DXers began chasing this new one in earnest.  The DXCC country count is back up to 340 and there is no doubt there will be enough ongoing activity from Kosovo by both the locals and visiting operators for every DXer to eventually confirm this one.


Registration for the 2018 International DX Convention (IDXC) in Visalia, California is available online at http://www.dxconvention.org/ .  CADXA will not be involved in the running of the convention this year.  The Southern California DX Club decided to do it all themselves.  After all of CADXA’s efforts last year to support the Northern California DX Club, our club is actually pleased to have the year off.  Many CADXA members will be there along with about 700 other DXers and a room full of vendors.
